There are only two advantages that I can see with the br600, weight, and the fact that all the major components are covered, so nothing can get snagged by a branch or something. As far as comfort goes i tried both of the blowers on, and they are both equally comfortable IMO, I like the waist strap on the husky and the big soft straps on the Stihl. As far as vibration goes the husky will rattle your teeth off at idle, but once you hit the gas it smooths right back out. Maybe I just have a bias towards husky since I've not been very pleased with the newer 4mix motors Stihl makes.
